CAUSES
Your SI joint provides stability for your body as it absorbs much of the shock during daily activities such as walking, running and sitting. The SI joint is the largest synovial joint in the body and is subject to damage by wear and tear, inflammation, or injury, leading to SI joint dysfunction. SI joint dysfunction changes the joint’s normal movement and can generate low back pain, which can often be debilitating.
Additional factors can also be contributing causes to SI joint dysfunction. Wearing of the cartilage of the SI joints over time can lead to arthritis which may develop into SI joint pain later in life. Previous back surgeries, trauma and pregnancy may also predispose a patient to SI joint dysfunction.2
